120HP 4WD Tractor with 1BZD Heavy Duty Disc Harrow for Large Dryland Preparation

The project requirement was based on a large dryland farming operation where maize, wheat, soybeans and other field crops could be planted. The land contained compacted soil, crop residue and uneven areas after primary tillage.

A light or small mounted disc harrow would not provide enough working width, weight or soil penetration for this application. The equipment therefore needed stronger cutting ability, stable field performance and a hydraulic transport system suitable for large-scale agricultural work.

• Break large soil clods after primary plowing
• Cut and mix maize stalks and other crop residue into the soil
• Level uneven dryland before planting
• Cover a larger field area with fewer passes
• Reduce excessive tractor wheel slip during heavy work
• Support hydraulic lifting for field and transport positions
• Match a medium or high-power four-wheel-drive tractor

Model selection should be confirmed according to the tractor horsepower, soil resistance, required working width and transport conditions. Final specifications are subject to order confirmation.

A heavy duty trailed disc harrow produces higher draft resistance than a small mounted harrow. The tractor must provide sufficient engine power, traction and operating weight to pull the implement steadily.

A 120HP 4WD tractor offers a practical balance between pulling power, working efficiency and fuel use for medium and large 1BZD models. Four-wheel drive helps distribute power to both axles, reducing wheel slip on loose or uneven soil.

The tractor can also be used with other implements for four-wheel tractors , including plows, rotary tillers, planters, trailers and mowers.

The 1BZD series uses an opposed disc arrangement to improve soil cutting and reduce side draft during operation. Its heavy structure helps the discs penetrate compacted soil and work through crop residue more effectively.

Compared with a light mounted disc harrow, the trailed heavy duty design is more suitable for wider working widths, large fields and demanding soil conditions. The hydraulic system also helps switch between working and transport positions.

• Stronger soil penetration: the heavy frame helps the discs enter hard or compacted soil.
• Efficient residue cutting: the discs cut maize stalks, weeds and other crop residue.
• Reduced side draft: the opposed disc arrangement supports more stable operation.
• Higher field efficiency: wider models can cover more land during each pass.
• Better tractor traction: the 4WD system helps reduce wheel slip during heavy harrowing.
• Convenient transport: hydraulic control supports movement between fields and transport areas.

1. Primary tillage: use a disc plow or other plowing equipment to open and turn the soil.
2. Heavy harrowing: use the 1BZD disc harrow to break soil clods, cut residue and level the surface.
3. Secondary preparation: perform another harrowing pass when finer soil preparation is required.
4. Planting: use a maize planter, grain seeder or other planting equipment after the soil reaches the required condition.

The working widths and tractor power ranges above are estimated references. Actual matching depends on soil hardness, moisture, working depth, disc quantity, tractor weight and field slope. Final data is subject to technical confirmation.

When the tractor and disc harrow are matched correctly, the combination can improve the condition of the field after primary plowing.

The expected results include smaller soil clods, improved field leveling, better residue mixing and a more suitable surface for planting equipment. The wider working width can also reduce the number of passes required on large farms.

Actual working efficiency varies according to tractor speed, soil resistance, field shape, working depth and operator experience.

• Large maize, wheat, soybean or cotton farms
• Agricultural service contractors
• Farm machinery dealers and distributors
• Land development and reclamation projects
• Farms replacing small or low-efficiency disc harrows
• Buyers requiring a tractor and implement package

Before selecting a model, buyers should provide:

• Tractor horsepower and drive type
• Farm size
• Soil type and moisture level
• Amount of crop residue
• Required working width
• Required working depth
• Field slope and transport conditions
• Destination country and port

Yes. A properly configured 120HP 4WD tractor can work with a suitable 1BZD heavy duty disc harrow. The final model depends on soil conditions, working depth and tractor specifications.

A heavy duty disc harrow normally has a stronger frame, larger or heavier discs and greater soil penetration. It is more suitable for hard soil, large fields and heavy crop residue.

Yes. The disc arrangement can cut and mix maize stalks and other crop residue into the soil. Performance depends on residue quantity, soil moisture and working speed.

Yes. Buyers can provide their farm size, soil conditions, required working width and budget. HENAN BEST Machinery (BSM) can recommend a matching tractor and farm implement package.
